SECONDARY OR STORAGE BATTERY.

Original application filed April 13, 1916 Serial No. 91,025. Divided and this application filed January 4,

- 1919. Serial No. 269,580.

To (all whom it maycomerml:

Be it known that I, BRUCE FORD, a citizen of the United States, and a resident of Philadelphia, in the county of Philadelphia :and

State of Pennsylvania, have invented certain connecting up a number of cells, but also provides a flexible inter-cell connection'consisting of comparatively few parts.

The invention will be claimed at the end hereof, but will be first described in connection with the accompanying. drawing, formr ing part hereof, and in which- Figure 1, is a side view of a portion of a cell provided with a battery terminal embodying features of theinvention, and

Fig.'2, is a face view of one of the terminals.

In the drawings the terminal 1 is rigid, while the terminal 2 is of unlike polarity and is flexible and comparatively long. One way of producing this relative rigidity and flexibility is by the use of appropriate materials, for example, lead alloyed with different proportions of antimony. Near the end of each terminal there is a bolt hole 3. Each of the cells is equipped in the manner described and in this way any confusion in con- Specification of Letters Patent.

Patented May 3, 1921.

necting up a number of cells is avoided and the cells may be connected by means of a single bolt, or the like, passed through the apertures 3 and this is a simple, expeditiousand safe method of connecting up the cells. Simple because the long terminals obviously must be connected to the short terminals and this insures the proper arrangement of polarity in the connection of the several cells, expeditious because there is but a single bolt to be applied, and safe, because the connection between the cells is flexible and so mechanically durable and unlikely to be broken or detached.

I claim:

1. A storage battery cell provided with a plate structure having terminals of opposite sign and whereof one is relativelyrig'id and the other relatively flexible and of greater length than the rigid terminal, sald terminals serving to avoid confusion in connecting a number of cells and to provide flexible inter-cell connections of compara tively few parts.

2. In a storage battery the combination of a plurality of cells each having a rigid terminal and a relatively long and flexible terminal, and all the rigid terminals being of one polarity and all the flexible terminals being of the other polarity, substantially as described.

3. In a storage battery the 'combination "of a plurality of cells each having a rigid terminal and a relatively long and flexible an adjoining cell, substantially as described.
